Here is what drives me crazy: 
if(undef, undef){
    print "OK1\n";
}

if( (undef, undef) ){
    print "OK2\n";
}

my @a = (undef, undef);
if(@a){
    print "OK3\n";
}

This prints OK3. According to the above, it should also print OK2 because (undef, undef) is a list of two elements that evaluates to 2 in scalar context. Still, it doesn't.
